DESCRIPTION

The HC2700 Series are Precision V oltage References

that use Thin Film Hybrid technology to achieve

extremely accurate, low temperature coefficient,

10 volt reference sources.

Nichrome Thin Film resistors on ceramic provide

excellent characteristics: low absolute and tracking

temperature coefficients, trimmable to high accu-

racy and superior long term stability.

K ey specifications for the HC2700 Series include:

untrimmed initial accuracy to 2.5 mV (0.025% ) max-

imum, drifts over temperature to 3 ppm C maximum.

and ± 5 mA drive minimum over the full operating

temperature range. Line and load regulation are

300 µV /V and 50 µV /mA maximum and long term

stability is also excellent, typically 100 ppm for 1000

hours at 25 C.

The HC2700 Series includes internal power supply

filter capacitors to insure continuous low noise

operation.

Three basic versions are available, the HC2700 for

+10 volt applications, the HC2701 for -10 volt

applications and the HC2702 for applications requir-

ing both +10 volt and'-10 volt sources which track

over temperature.

The HC2700 Series is packaged in standard 14 pin

Dual-in-Line packages and 28 pin LCC. M odels are

available fully compliant to M IL-STD-883 for military

and aerospace applications.
